[0016] Beneficial Effects

[0017] The present invention provides a mechanical automatic grasping device for an assembly line. Compared with the prior art, it has the following beneficial effects:

[0018] 1. The assembly line uses a mechanical automatic grasping device. When it is necessary to clamp an object with a flat surface, it is only necessary to unfold the two clamping plates on both sides so that the two clamping plates remain in a flat state. At this time, the two clamping plates on both sides can fit with the surface of the object with a flat surface, and then the two clamping plates on both sides can be driven to approach each other by rotating the bidirectional screw, thereby completing the clamping of the object with a flat surface. When it is necessary to clamp an object with a curved surface, first move the two clamping plates on both sides close to the curved surface object, and then turn on the second motor to drive the second rotating rod to rotate, and the slider on the second rotating rod will rotate accordingly, thereby driving the sliding The bevel gear rotates, and the sliding bevel gear meshes with the first bevel gear, which is fixedly connected to the rotating gear below. One of the rotating gears rotates, and the other rotating gear is driven to rotate in the opposite direction through the meshing relationship, so that the two first rotating rods drive the clamping plates to rotate, so that the two clamping plates are V-shaped and fit on the surface of the curved object. At this time, the curved object can be clamped and grasped. Through the coordinated action of components such as the bidirectional screw, rotating gears and bevel gears, the position and angle of the clamping plate can be quickly and automatically adjusted to adapt to objects on different planes, which greatly saves the time for replacing the clamping components and significantly improves the efficiency of grasping objects on the assembly line.

[0019] 2. The mechanical automatic grasping device used in the assembly line may have an angle deviation on the objects on the assembly line, which will affect the grasping effect of the objects. At this time, the third motor is turned on, and its output shaft drives the second gear to rotate, and the second gear meshes with the first gear, thereby driving the rotating shaft to rotate. Since the rotating shaft is fixedly connected to the housing, the housing and the entire adjustable grasping assembly will rotate around the rotating shaft to adjust the grasping angle, so that the angle of the adjustable grasping assembly can be further accurately adjusted, thereby improving the grasping effect of the objects on the assembly line.

[0020] 3. The mechanical automatic grabbing device for the assembly line is equipped with a visual recognition camera, which enables the grabbing device to quickly and accurately identify the position and shape of the material, and then control the electric slide rail to drive the mounting plate to move along the preset path through its output end, so that the entire grabbing device can operate at different positions of the assembly line. The electric push rod on the mounting plate can adjust the height of the casing according to actual needs to adapt to materials of different heights. The mutual cooperation of the electric slide rail and the electric push rod can realize the precise control of the position, height and grabbing action of the grabbing device, ensure the accuracy of grabbing and placement, and help improve product quality and production stability.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides two technical solutions:

[0030] Figure 1-Figure 6 The first embodiment is shown: a mechanical automatic grasping device for an assembly line, comprising a placing rack 1, an electric slide rail 2 is arranged at the top of the placing rack 1, a moving component 4 is arranged below the output end of the electric slide rail 2, and an adjusting grasping component 5 is arranged below the moving component 4;

[0031] The adjustable grab assembly 5 comprises two mounting frames 55, and two first rotating rods 56 are rotatably mounted on the outer wall of the mounting frames 55. The outer walls of the two first rotating rods 56 are fixedly sleeved with clamping plates 57. The top ends of the two first rotating rods 56 penetrate the top ends of the mounting frames 55 and are fixedly mounted with rotating gears 58. The two rotating gears 58 are meshedly arranged. When one rotating gear 58 rotates, it can drive the other rotating gear 58 to rotate in the opposite direction. The rotating gear 58 can then adjust the angle between the two clamping plates 57 through the first rotating rods 56, so that the two clamping plates 57 can adapt to objects with flat surfaces or curved surfaces, so as to facilitate clamping of objects with different planes.

[0032] The moving assembly 4 includes an electric push rod 41, a frame 42 is fixedly mounted on the bottom end of the electric push rod 41, a rotating shaft 43 is rotatably mounted on the bottom end of the frame 42, a first gear 44 is fixedly mounted on the outer wall of the rotating shaft 43, and a second gear 46 is meshedly arranged on the outer wall of the first gear 44.

[0033] The adjusting and grasping assembly 5 also includes a casing 51, and a bidirectional screw 52 is rotatably installed on the inner wall of the casing 51. The outer wall screw of the bidirectional screw 52 is connected to two movable sliders 54, and the outer walls of the two movable sliders 54 are fixedly connected to two mounting frames 55 respectively. When the bidirectional screw 52 rotates, it can drive the two movable sliders 54 to approach or move away from each other, and the movable slider 54 then drives the two clamping plates 57 on both sides to approach or move away from each other through the mounting frame 55, so that objects can be grasped and put down. Two vertical plates 59 are fixedly installed on the outer wall of the casing 51, and a second rotating rod 510 is rotatably installed between the opposite sides of the two vertical plates 59, and two sliding strips 511 are fixedly installed on the outer wall of the second rotating rod 510.

[0034] The outer wall of the second rotating rod 510 and the two slide bars 511 is slidably connected with a sliding bevel gear 514, and the sliding bevel gear 514 can slide on the second rotating rod 510 and the two slide bars 511, and due to the setting of the slide bar 511, when the second rotating rod 510 rotates, it can drive the sliding bevel gear 514 to rotate, and the outer wall of the sliding bevel gear 514 is rotatably installed with a connecting plate 513, and the bottom end of the connecting plate 513 is fixedly connected to the mounting frame 55. When the movable slider 54 drives the mounting frame 55 to move, the mounting frame 55 can drive the mounting frame 55 through the connecting plate 513. The sliding bevel gear 514 slides on the second rotating rod 510, and since the sliding bevel gear 514 is rotationally connected to the connecting plate 513, when the sliding bevel gear 514 rotates, it will not interfere with the connecting plate 513. The outer wall of the sliding bevel gear 514 is meshed with a first bevel gear 515, and the bottom end of the first bevel gear 515 is fixedly connected to the top end of one of the two rotating gears 58 below. When the sliding bevel gear 514 rotates, it can drive the first bevel gear 515 to rotate, and the first bevel gear 515 then drives a rotating gear 58 to rotate.

[0035] Figure 1-Figure 6 A second embodiment is shown, which mainly differs from the first embodiment in that two movable sliders 54 are movably inserted into the inner wall of the casing 51, and rubber pads are fixedly installed on the outer walls of the four clamping plates 57. The rubber pads can prevent the clamping plates 57 from damaging the surface of the object, and the rubber pads can increase the friction of the clamping plates 57 on the surface of the object. A first motor 53 is fixedly installed on the outer wall of the casing 51, and the output shaft of the first motor 53 passes through the inner wall of the casing 51 and is fixedly connected to one end of the outer wall of the bidirectional screw 52. The first motor 53 can drive the bidirectional screw 52 to rotate.

[0036] A second motor 512 is fixedly mounted on the outer wall of one of the two vertical plates 59 . The output end of the second motor 512 passes through the outer wall of the vertical plate 59 and is fixedly connected to one end of the outer wall of the second rotating rod 510 . The second motor 512 can drive the second rotating rod 510 to rotate.

[0037] The output end of the electric slide 2 is fixedly installed with a mounting plate 3. The electric slide 2 is a prior art, mainly composed of a screw and a power source, and can drive the mounting plate 3 to move linearly. The outer wall of the mounting plate 3 is fixedly connected to the electric push rod 41. The electric push rod 41 is a prior art, and can drive the clamping plate 57 to adjust the height. The rotating shaft 43 is fixedly connected to the housing 51, and the top of the frame 42 is fixedly installed with a third motor 47. The output shaft of the third motor 47 passes through the top of the frame 42 and is fixedly connected to the second gear 46. The third motor 47 drives the second gear 46 to rotate, thereby driving the first gear 44 and the rotating shaft 43 to rotate, so as to control the angle adjustment of the clamping plate 57 below. The bottom end of the frame 42 is fixedly installed with a visual recognition camera 45.

[0038] The visual recognition camera 45 is electrically connected to the electric slide rail 2, the first motor 53, the second motor 512, the third motor 47 and the electric push rod 41 respectively. The visual recognition camera 45 is a prior art that can monitor and capture images of objects on the assembly line in real time, and then control other electrical components through the position information of the object, so as to adjust the position, height and angle of the clamping plate 57, thereby improving the grasping effect of the object.

[0039] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0040] During operation, when it is necessary to grab and carry objects on the assembly line, the device is first placed at a suitable position on the assembly line. When an object enters its field of view, the visual recognition camera 45 quickly captures the image information of the object, and then controls the electric slide rail 2 to start, and drives the mounting plate 3 to move along the preset path through its output end, so that the entire grabbing device can operate at different positions of the assembly line. The electric push rod 41 on the mounting plate 3 can adjust the height of the housing 51 according to actual needs to adapt to materials of different heights. The visual recognition camera 45 analyzes the angle information that needs to be adjusted and transmits it to the control system of the third motor 47. The third motor 47 is started, and its output shaft drives the second gear 46 to rotate, and the second gear 46 meshes with the first gear 44, thereby driving the rotating shaft 43 to rotate, so that the housing 51 and the entire adjustment grab assembly 5 rotate around the rotating shaft 43 and adjust to a suitable grabbing angle. The mutual cooperation of the electric slide rail 2, the electric push rod 41 and the third motor 47 can realize the precise control of the position, height, angle and grasping action of the grasping device, ensure the accuracy of grasping and placing, and help improve product quality and production stability. Then, the clamping plate 57 is moved to a suitable position. When it is necessary to clamp an object with a flat surface, it is only necessary to unfold the two clamping plates 57 on both sides so that the two clamping plates 57 remain in a flat state. At this time, the two clamping plates 57 on both sides can fit with the surface of the object with a flat surface, and then turn on the first motor 53. The first motor 53 drives the bidirectional screw 52 to rotate. During the rotation of the bidirectional screw 52, ​​the two clamping plates 57 on both sides can be driven to approach each other by moving the slider 54 and the mounting frame 55, thereby completing the clamping of the object with a flat surface. When it is necessary to clamp an object with a curved surface, first unfold the two clamping plates 57 on both sides. The second motor 512 is turned on to drive the second rotating rod 510 to rotate, and the sliding bar 511 on the second rotating rod 510 rotates accordingly, thereby driving the sliding bevel gear 514 to rotate, and the sliding bevel gear 514 meshes with the first bevel gear 515, and the first bevel gear 515 is fixedly connected to the rotating gear 58 below. One of the rotating gears 58 rotates, and the other rotating gear 58 is driven to rotate in the opposite direction through the meshing relationship, so that the two first rotating rods 56 drive the clamping plates 57 to rotate, so that the two clamping plates 57 are V-shaped and fit on the surface of the curved object. At this time, the curved object can be clamped and grasped, and the coordinated action of the two-way screw 52, ​​the rotating gear 58 and the bevel gear and other components can quickly and automatically adjust the position and angle of the clamping plate 57 to adapt to objects on different planes, which greatly saves the time for replacing the clamping components and significantly improves the grasping efficiency of objects on the assembly line.
